Croup is a common respiratory illness caused by a viral infection.
It can cause swelling of the upper airway, including the windpipe (trachea), voice box (larynx) and vocal cords. This swelling can lead to a hoarse voice, barky cough and sometimes difficulty breathing. It occurs most often in babies and children up to 3 years of age because their airways are smaller, but older children can also get it. Croup most often happens in the fall and winter months, but it can happen in any season.
